Subject: [PATCH 05/10] gpio: rda: Make IRQ optional
Date: Fri, 19 Sep 2025 01:48:45 +0700	[thread overview]
Message-ID: <20250919-rda8810pl-mmc-v1-5-d4f08a05ba4d@mainlining.org> (raw)
In-Reply-To: <20250919-rda8810pl-mmc-v1-0-d4f08a05ba4d@mainlining.org>

From: Dang Huynh <dang.huynh@mainlining.org>

Not all GPIO have IRQ. When we use this driver with
GPIOC (handled by modem) we get:

rda-gpio 11a08000.gpioc: error -ENXIO: IRQ index 0 not found

Let's mark IRQ as optional so this error doesn't show up.
